Should be fixed in repository.

It would be nice if such incompatible / code breaking changes would be announced in the changelog or readme. (Hiding in a long list of all changesets is not user friendly.)
Even better would be if they could work around such issues and maintain a stable interface especially when it is an external library which is used by several other programs.
